Abstract: The present disclosure describes a system and method of performing failover in a storage area network. In one embodiment of the present disclosure, a computer network includes a host and a storage system associated with the host. The storage system has a first controller with a first port and a second controller with a second port. The first controller is assigned a common node name and the first port is assigned a first port name. The second controller is assigned a common node name and the second port is assigned a second port name. More specifically a multipathing driver is operable to determine a signal path for a communication sent to a storage device associated with the first controller and the second controller and operable to perform failover operations if the signal path fails.

Failover processing in a storage system
Richard Meyer,Kumar Gajjar,Chan Ng,Andrey Gusev +3 more
- 13 Feb 2002
TL;DR: In this paper, a failover recovery approach encapsulates the knowledge of failureover recovery between components within a storage server and between storage server systems, including information about what components are participating in a Failover Set, how they are configured for failover, what is the Fail-Stop policy, and what are the steps to perform when "failing-over" a component.

System and method for policy based storage provisioning and management
Kumar Gajjar,Jim Collins,Richard Meyer,Chandra Prasad,Dipam Patel +4 more
- 13 Feb 2002
TL;DR: In this article, a storage provisioning policy is created by specifying storage heuristics for storage attributes using storage heuristic metadata, which are defined to express a rule or constraint as a function of a storage attribute.

Data storage network with host transparent failover controlled by host bus adapter
Choon-Seng Tan,Michael White,Greg J. Pellegrino +2 more
- 28 Dec 2001
TL;DR: In this paper, a failover and failback mechanism in a host bus adapter linked to a host server is described. But the failureover mechanism is not transparent to the host computer device, as the host is not required to participate in the failover processes.

- 07 Jun 1995
TL;DR: In this article, the number of disk accesses to the disk drive is monitored and a histogram is generated to display the distribution of disks accesses over time, and a network administrator subsequently selects time intervals to spin down one or more of the disk drives during periods of disk inactivity.
